Suricata fails to start

  • Increase the memory for the Stream Memory Cap

  • You have an eight-core CPU, so as @ntct says, increase the Stream Memcap value on the FLOW/STREAM tab to at least 256 MB and try to start again.  Keep increasing the value in 4 MB or 8 MB chunks until Suricata starts.  You can then try backing it down if you wish until it breaks, then bump it up slightly.  Some changes in the Suricata binary in a recent revision caused an increase in needed stream memory when using high core-count CPUs.  The old default of 32 MB is too low.
